Fantasy Tip: Mariota threw a questionable ball that was picked off by Bene Benwikere on the first drive, but he was otherwise flawless, routinely hooking up with rising undrafted free agent Tajae Sharpe during their three drives together. Last year's No. 2 overall pick is 14-for-15 in exhibition play and should be considered as a high-upside QB2 given his efficiency and ability to generate fantasy points with his feet.

Dallas Cowboys QB Kellen Moore replaced QB Matt Cassel during the team's Week 15 game, but head coach Jason Garrett is not ready to name Moore the starting quarterback for the final two games of the season. Moore went 15-for-25 for 158 yards, one touchdown and three interceptions during the game.

Fantasy Tip: Cassel was benched after he struggled at the start of the game, but Moore did not do a whole lot better when he entered the game. Owners can monitor the situation to see who receives the start, but owners should avoid both players.

Fantasy Tip: There was reason to think that Cassel could be benched after his dismal Week 14 performance. Plus, he's only thrown one touchdown in his last four games, and the schedule doesn't get easier as Dallas hosts the New York Jets next week. Continue to stay away from Cassel.

Fantasy Tip: Cassel did nothing to help FantasyScore owners who took a chance on him, and he did very little for Dez Bryant fantasy owners until the final few minutes, too. Cassel cannot be trusted for fantasy purposes in Week 14 against the Green Bay Packers.

Dallas Cowboys QB Matt Cassel is the starting quarterback again with QB Tony Romo (clavicle) out for the rest of the year. The Cowboys expect Romo to be 100% for the offseason program in March. QB Kellen Moore will likely be added off the practice squad to back up Cassel.

Fantasy Tip: Cassel was winless filling in for Romo earlier this season, and there's no reason to think that he'll drastically turn things around to close out the year. There's nothing to like about Cassel on FantasyScore, really, and you should look to downgrade the likes of Dez Bryant, Jason Witten, Terrance Williams and Cole Beasley in the passing game, too.

Fantasy Tip: While Cassel ($4,800, 9.6% of cap) is coming off a three-touchdown, 299-yard performance last week, and the Buccaneers have allowed the second most passing touchdowns for the season, Cassel still carries plenty of risk in all fantasy formats. He is a viable No. 2 QB in two-quarterback leagues, and a potential source of cap relief at FantasyScore for Week 10.
